The end I! of the shaft is driven in the is wound up tighter than desired. In other words, customary and well 2 known manner from the it is not possible to wind as soft a roll with the paper making or treating machine with which drum type reel as with the driven spool type of the reel is associated so that the drum l3 will 5& reel. have a peripheral speed substantially equal to not deem it necessary to enter into a detailed description of the same. Fixedarms l3 and II are attached to the top of the brackets 3 and 3 and extend outward on the receiving side of the machine as best shown in Figure l. A spreader roll 2| extends between the ends of the arms I3 and "and is carried on bearings 32 supported on the outwardly extending ends of the arm by means of screws 23 having threaded engagement with collars 24 positioned between bifurcations 23- and 33 on the ends of the arm. Through rotation of the collar 24 the spreader roll may be adjusted to maintain the sheet taut throughout its width. The upper surfaces of the arms 13 and i3 serve to define a reserve position for the windingv spool as will presently appear.

The spool, one of which is indicated generally at 31, comprisesa'central core 23 having a shaft 23,the endsof which project from the core 23; as shown at- "and 33. The projecting ends of the shaft 33 each carry a bearing designated generallybythe numerals" and 34..- Each of the bearings has a plurality of annular recessesvon its outer surface. as indicated at 33, 33 and 31 (Fig. 3). these recesses serving in the transfer of the spool from position to position. The outer recesses 33 of the bearings'are of such width as to receive the upper edges of the arms i3 and I3 inthe reserve position of the spool; The spools 31 are held in the reserve position by meansof starting arms, designated generally by the numerals 33 'and 33, positioned to register with the annular recesses 31 on the bearings 33 and 34. The starting arms are carriedv on hubs 4| and 42 positioned on the sleeves ii and I2 and rotatable thereon. Gear segments 43 and 44 are also carried on the hubs 4i and 42 below the winding drum in a position to engage driving means for rotating the arms 33 and 33 so as to permitthe spool to roll off the arms l8 and l3 into contact with the outer surface of thewinding drum II. as shown in Fig. 2, and to a subsequent transfer position as will presently be explained. The segments 42 and 43 are driven by spur gears 45 and 43 carried on the shaft 4;! which is, in turn, journaled in the frame 111G111? bers 3 and I. The front end of. the shaft 41 extends beyond the frame member 3, as shown at 43,:and carries a hand wheel 43 and a gear 3|. The hand wheel serves for manual rotation of the shaft 41 while the gear 3| cooperates with a pawl 32 to normally look the shaft '41 against rotation. The pawl 32 slides through .a retainer 33 and is pivotally supported on a foot lever 34, as shown at 33, the foot lever being pivotaily carried on the frame member 3, as shown at 33. A spring "acts to retain the pawl 32 in forward engaged position.

The sheet of paper enters the reel under the spreader roll 2| and passes over the drum l3, as best shown in Figure l. The operator brings the parts into the initial winding position by depressing the foot lever 34 and rotating the hand wheel 43, thereby rotating the arms 33 and 33 into the position shown in Fig.2. In this position, the

core 23 of the spool is in surface contact with the winding drum l3-and the bearings 33 and 34 are in'contactwiththe starting arms 33' and 33. The operator thereupon severs the paper on the oifgoing side of the winding drum in the usual manner and causes it to follow the surface of the spool to start the paper winding on the spool.

As soon as practicable am ne winding is started in the initial winding position as described, the spool is transferred to a normal winding position in which the major part of the winding operation is conducted. In this posi tion the spool is carried on a pair of winding arms designated generally by the numerals 33 and 33. Each of-thewinding arms has a yoke 3| attached to the upper end thereof and carriedin ways 32 for adjustment transversely of the arms by means of a screw 33 threaded into a boss 34 on the-yoke and carrying a hand wheel 33 for rotation of the screw. Through this means, the-yoke may be adjusted on the winding arm to bring1about proper alignment of the spool. The winding arms 33 and 33 are so spaced that the yokes register with the annular recesses 33 on thelspool bearings 33 and 34. Thus, the spool bearings seat in the cradles 3| and the cradles 'idturriseat in the recesses 33 of-the bearings so as to prevent endwise movement of thespool'. The lower ends of the winding arms 33 and 33 are keyed as shown at 33 to a shaft 31 extending from front to back of the machine, thefront end of the. shaft being journaled in the frame member 3 and the back end of the shaft being carried in a frame member 33, the

shaft being journaled in these two-frame members for rotation. The front end of the shaft 31 carries a gear segment 33 positioned within the' a frame member 3 and meshing with a pinion ll carried on a shaft," within the. frame member The shaft 13 also carries a gear 13 meshing /with a pinion 14 on a shaft 15 which carries the Jena wheel n on the forward side of the frame member. 3.. ,It will 'be noted that the frame member 3 is carried 0litward,. as shown at I1,

to provide a housing or chamber for the gears just mentioned. A set screw 13 is positioned in the frame member 3 to abut the end of the gear segment 33Itodetermine the winding position of the arms 33 and 33 and a spring pressed pin 13 is positioned for reception in an opening 3| in the gear segment when the winding arm (occupies the winding position to prevent accidental move- -ment of the winding arm.

The spoolis transferred from the starting or initial winding position by rotation of the hand wheel 13 in a direction to bring the winding arms 33 and "into a position adjacent the winding drum such asshown in- Fig. 5. Thereupon, the hand wheel 43 is rotatedin a direction to bring the starting arms 33 and 33 in a counter-clockwise direction'facing Fig. 5, thereby vpermitting the spool to move along the surface of the winding drum in a counter-clockwise direction until the spool'bearings 33 and 34 seat in the cradles 3i of the windingarms. Movement of the hand wheel 43 is continued until 'the starting arms reach a position free of the sweep of the spool as it moves into the winding position. Rotation of the hand wheel 13 in the opposite direction will then bring the winding arms into the normal winding position shown in Fig. 2.

Means are provided for driving the spool independently of the winding drum l3. This means is operative to establish driving relationship with the spool while it occupies its starting or initial winding position and to maintain the driving relation while the spool is transferred into the normal winding position and to complete the winding of the spool in the normal winding position. This means includes an arm 32 having one end fixedly carried on the shaft 31, the opposite end thereof projecting upward and carrying a bearing 33 longitudinal sliding movement thereon, a key 9|;

I The rod I03 is maintained in either of two opposed limit positions by means of a'spring pressed toggle I05 acting between the arms 82 and the end of the rod I03. The rod I 03 also carries a finger I08 1 longitudinally spaced from the end of the spool when the spool is seated in the cradles 6i. A shaft 84 is carried in the bearing, and projects inward to a point spaced from the end of the spool, as shown'in Fig. 3. The rear end of this shaft carries a pulley 85 driven by means of a belt 86 from a motor 81; A sleeve 88 having a flange 89 is, carried on the front end of the shaft 84 for preventing rotation of the sleeve with respect to the shaft, The flange 88 carries a flexible disk 92 i, coaxial-with the shaft 84 and having a central opening 93 for the passage of the ends cf'the shaft upon longitudinal movement of the sleeve 88. Carried on the disk 92 is an electromagnet 94 adapted to engage a flange til-keyed to the end 32 of. the spool shaft. Conductors fl andal- I of conductive materialjare adapted to be engaged by brushes, not shownyfor the purpose of supply-,

ing electrical energy "to*:";the ele'ctr'oma'gnet" 94. These brushes are connected to a switch 88 for, the purpose of controlling the supply of current to the magnet as will presently be described.

The sleeve is moved from a position in which the electromagnet engages message 9S tof-a re tracted position by means of a collar 89 engaging the sleeve 88, a lever IOI pivotally engaging the collar 99 and being pivotally. supported upon the arm 82, as shown at I02. The lever IOI is rotated about the pivot point j I 02 bymovement of a irod I03 extending from front to back of the machine, as shown in Fig. 3 and 4, the rod being manually movable longitudinally by means of a handle I 04.

adapted .to actuate the lever of the switch so as to shut off the current to the electromagnet 841 when the rodoccupies its forward position as shown in Fig. 4, and to close the circuit to the magnet when the rod occupies therearward position, as shown in Fig. 3.

Driving connection to the spool is'preferably established when the winding arms 58 and 59 00- cupy the position shown in Fig. 5." .This is-accomplished by inward movement ofthe handle I04,

whereby the sleeve 88 is movedtso as to engage the electromagnet 94 with the flange of the spool and simultaneously close the switch 98,

whereupon the electromagnet is energized. The

driving motor 81 is preferably designed to run continuously and to be controlled by an independi ent switch, positioned'as may be desired by the operator. a

In accordance with the'usual practice, the spool,

when occupying the normal winding position, is

drivenat a rate to maintain a constant or a predetermined tension on the sheet being wound.

Any of numerous well known devices may be employed-for-accomplishing this drive. Since the specific form of drive is not apart of the present invention, I have not shown the details of the construction whereby the motor 81 is caused to drive the spool to maintain constant tension on the sheet. However, one satisfactoryform of such f drive .is known as the Reliance constant-tension drive, and comprises a generator driven from the winding drum I3, the generator being connected to the motor 81 in such manner as to give con-' stant tension in the sheet. This type of drive in both electrical and hydraulic mechanism is well known in the art. t

In use, the operator carries the parts through the following cycle: Assuming the parts to be in the position shown in Figure 1 and the spool of paper "being wound to its desired diameter, the operator rotates the wheel 40, thereby moving therstarting arms 88 and 39 into the position shown in Fig. 2, whereupon the spool carried in the reserve position on the arms I8 and I9 rolls down into theinitial driving position. The sheet is thensevered on the oifgoing side of the winding drum and caused to follow the newly positioned spool. The handle I04 is then drawn out ward to thepositionshownin Fig. 4, releasing 'the drive on the wound roll. The wound rollmay then be liftedfrom the cradle by a crane or other suitable means. In the meantime, the winding of'the sheet has been well started on the newly positionedspoolso that the winding .arms 58 and 89 may 'beswung into the position shown, in

Fig. 5 and thenew 1 spool received .within the circumstances the sheet may be started on the spool ina smooth and uniformmanner without the lossxoi a great deal of paper in accomplishing the starting operation. Likewise, the sheet starts smoothl'yand evenly on the roll so that lumps and bulges are not produced at the center of the roll, resulting in the ,weste of a considerable amount of paper whenthe sheet is re-wound.

After the initial winding of .the sheet, the spool is transferred as soon as practicable into the .nor-

"malwinding positioziinwhich the spool and the roll of paper are free of the windingdrum, In

this winding position, the best winding characteristics are obtained and the winding operations are freeof the difliculty commonly associated with the winding of a roll against the surface of a winding drum, such, for example, as the production of wrinkles inthe sheet and soft spots in i 'the roll.

Another, advantage of my improved reel lies in the ease with which the paper can be handled when a break has occurred. With the old driven spool type of reel, when a break occurs the operators have to carry the sheet around the moving spool by hand and fold the end in between the sheet and thereel to start the winding up operation again. At any appreciable speed this is a very difllcult operation and usually ,is accompanied by a considerable loss of paper. With the reel of my invention, if a break should occur the partiallyfound reel of paper is lowered into contact with the drum, and when the sheet is ready to be placed on the' reel again, it-will be passing between the partially wound reel and the drum, thus. controlling the draw from the paper machine or;its calenders'. The operators thenneed only tear off any excess paper and throw'theend of the sheet up aroundthe par tially wound reel by hand or by means of an air Jet in order to start winding up again. As soon as the endv is securely wound onto the reel, the

reel is taken away from the drum as when startinganewone.

another advantage of my improved construction is the fact thatrit permits getting a good hard start when the paper is wound on anew spool whereupon the tension may be relieved as the reel builds up. The hard start is, of course,

secured when the new spool is on the drum andv the sheet is being started around it, and then by moving the arm 38 and 39 down from the starting point gradually, the tension with which the paper is wound can be somewhat diminished to the point where the spool is transferred to the arms 58 and 59 and from the time when these arms take the spool. the tension can be still further reduced by operating whatever drive is supplied for the spool when in these arms. This feature of a hard start and a controlled tension during the balance of the winding is something which cannot be readily secured with the ordinary driven spool type of winder because the be hardened up without getting into wrinkles and other difficulties, and it is frequently the case that the comparatively loose layers at the spool cause the paper to move sidewise on the i reel, sometimes spoiling the entire reel.

I have provided improved means for the transfer of the spool from position to position during the winding operation and for retaining a fresh spool in a reserve position. I have also provided improved means-for holding a fresh spool in a reserve position and for bringing the new spool bination, a driven winding drum, a spool adapted into operative position with respect to the drum and into a position for the transfer of .the spool from its initial winding position to its normal winding position.

Another feature of the invention lies in the provision of improved means for supporting the spool in its normal winding position and of improved means for affecting the drive of the spool in its normal winding position and during the transfer of the spool from its initial positionto its normal winding position.
